Question

Solve for x .

Answer 1

\[\large \bf If~ [\cos^{-1} x]=[\sin^{-1}x ] ~~where ~[.]=G.I.F\]

Answer 4

we can solve it this way
Let y = cos^-1(x)
then cos(y)= x

also, we are given that y = sin^-1(x)
and that means sin(y)= x

Answer 5

got it, let's try graphing the GIF of both equations
original graph of inverse cosine: http://goo.gl/sMQsP2
original graph of inverse sine: http://goo.gl/b4qSBD

Answer 6

just for the record

Answer 7

The graph starts from above 2 and goes down
the floor function works like 2.999 to 2 makes the GIF a horizontal line at 2
once it passes 2 at x=-0.425... it goes to 1.999 to 1
etc
and the graph would look something like this
do you kinda get it? :3
